Karl Denke, born on August 12, 1870, in Münsterberg, Silesia (now Ziębice, Poland), was a German serial killer and cannibal known as the “Cannibal of Münsterberg” or “The Forgotten Cannibal.” Operating between 1903 and 1924, he is believed to have murdered and cannibalized at least 30 to 40 homeless vagrants and travelers. Denke, often called “Papa Denke” due to his outwardly kind and religious persona, was a respected figure in his community, volunteering as a cross-bearer and organist at the local Lutheran church until he left in 1906.

Born into a wealthy farming family, Denke was a quiet, soft-spoken child who struggled academically and ran away from home at age 12. After his father’s death at age 25, he used his inheritance to buy land, but his farming venture failed, leading him to sell the property and settle in a small apartment on Stawowa Street. There, he ran a shop selling leather goods and boneless meat, which authorities later suspected contained human remains. Denke lured victims with promises of money or shelter, killed them by bludgeoning or strangling, and dismembered their bodies, using their flesh for consumption or sale as “pork” at local markets. He also crafted items like belts and shoelaces from human skin and hair.

His crimes went undetected for over two decades until December 21, 1924, when a victim, Vincenz Olivier, survived an axe attack and alerted authorities. Initially dismissed due to Denke’s reputation, Olivier’s claims prompted a police investigation. Denke was arrested but hanged himself in his cell before interrogation. A search of his home revealed gruesome evidence: jars of pickled human flesh, over 300 human teeth, 480 bones, blood-stained clothing, and a ledger detailing at least 31 victims, including names, dates, and “slaughter weights.” His first known victim was Ida Launer in 1903, followed by Emma Sander in 1909, among others.
